Synopsis

Following the conclusion of SPLIT, GLASS finds David Dunn pursuing Kevin Crumb’s superhuman figure of The Beast in a series of escalating encounters, while the shadowy presence of Elijah Price emerges as an orchestrator who holds secrets critical to both men.

This is the third installment of a trilogy consisting of M. Night Shyamalan's previous films, Unbreakable and Split. The former debuted in 2000 and quickly earned a passionate following. Its depiction of a grounded superhero drama was seen as being ahead of its time. Talk of a sequel went on for several years, but such a film never got off the ground. 2017's Split surprised viewers with a twist that confirmed it was set in the Unbreakable universe.

Shyamalan confirmed he was working on Glass in February 2017, shortly after Split was released in theaters. The film was set for a 2019 release date in April of that year, and it was also confirmed the principal players from Unbreakable and Split would be returning. Principal photography started in October 2017.
